What undercoating do you guys recommend?
 

I purchased 4 cans of the 3M stuff today off Amazon because I plan to do the bottom of my truck.

I was looking for something kind of generic but this stuff wasn't too much more expensive so I just went with it. Reviews look pretty good so I'll see how it holds up. Still better than not having anything I guess. :)

ive always just gone the POR 15 route.



cheap and shiny
